[microsound] beginning-less universe

[Bård Harazi Farbu <bardfarbu@xxxxxxxxx>]

Hi all

Read this in Wired today:

	According to Turok, who teaches at Cambridge University, the Big  
Bang represents just one stage in an infinitely repeated cycle of  
universal expansion and 		contraction. Turok theorizes that neither  
time nor the universe has a beginning or end.

	"Imagine you have a room full of air, with all these molecules  
banging around. The vast majority of time, these molecules spread  
uniformly -- but once in a trillion 	trillion years, they all end up  
in the corner of the room. If you look at the room and run the clock  
forward, they'll eventually make themselves uniform: But it would 		 
reverse, and you'd watch them flying into the corner. Then they'd fly  
out again.

	If this is right, it means that time runs forward for a while. Then  
there's a random state without an arrow of time, then time runs  
backwards, and then time runs forward 	again. That's the bigger  
picture: We're still very far away from understanding it, but that  
would be my bet. "

	In our picture, there was a universe before the Big Bang, very much  
like our universe today: a low density of matter and some stuff  
called dark energy. If you 		postulate a universe like this, but the  
dark energy within is actually unstable, then the decay of this dark  
energy drives the two branes together. These two branes 	clash and  
then, having filled with radiation, separate and expand to form  
galaxies and stars.

	Then the dark energy takes over again. It's the energy of attraction  
between the two branes: It pulls them back together. You have bang  
followed by bang followed by 	bang. You have no beginning of time.  
It's always been there.

Would't it be neat with a microsoundpiece modeling the beginning-less  
and never-ending universe presented in this theory?
